The present disclosure provides a heavy ion beam real-time monitoring device and an irradiation test system. The device includes a detection structure and an aperture structure. The detection structure includes a plurality of detectors for real-time monitoring of the heavy ion beam; The incident path of the ion beam is set before the detection structure; wherein, the aperture structure includes an aperture member, and the aperture member includes a plurality of detection aperture groups, which are arranged through the aperture member, wherein each detection aperture group includes multiple There are two detection apertures with different apertures, and one detection aperture group corresponds to one detector among the plurality of detectors; the aperture member rotates with the center line of the aperture member as the rotation axis to switch between one detection aperture group One detection diaphragm of different apertures corresponds to one detector. The disclosed device can realize real-time and large-scale monitoring of the fluence rate and uniformity of the heavy ion beam during the sample irradiation process, the monitoring accuracy is high, and there is no need for frequent disassembly and assembly during the irradiation process. Replacing the aperture greatly improves the test efficiency.
Description
technical field [0001] The disclosure relates to the technical field of heavy ion detection, in particular to a heavy ion beam current real-time monitoring device and an irradiation test system. Background technique [0002] In the prior art, most single event effect irradiation experiments for heavy ions adopt the method of placing a beam-limiting diaphragm at the front end of the detector for beam current monitoring. The beam diagnosis system of the irradiation device in the prior art mainly adopts the installation of a scintillator detector with a beam-limiting aperture outside the beam line to monitor the size and uniformity of the fluence rate in real time. For example, a plastic thin film scintillator detector is directly installed on the beam line. The thickness of the thin film detector is small, and a small amount of energy can be lost when the beam penetrates the film to realize real-time monitoring of the beam. However, the beam-limiting diaphragms in the prior a...
